To all `whom it may concerns Be it known 4that I, A.v W'. BRI'NKERHOFF, l

to the letters of reference marked thereon, in

The nature of invention consists in that y peculiar construction of corn-planters whereby l. can combine with the main fremework,

.which is used formarking the ground prepare story to planting, an additional or upper frumc-v work containing the shoes, seeding devices,y

und attendants seat, and again remove the same therefrom without in the least impairing either ot' the parte; als0,`in so combining with the upper -oradditional vfrance-workv u; weighted lever for the purpose Aof producing the automatic elevation ot' the additional frame-work, and keeping the Isame above `the ground stell times, except when mounted by the attendant, thereby dispensing with the necessity o`f a second attendant for thatv pur,-

pose alsoin-` providingthe "seeding-cylinder y with oblique grooves' to insure an even. and

certain supply of seed at each operation of the l shaft, and also' with vthe elastic cnt-o betrtfeenv themetalli'c base and cap,whih: may', by means of' the' screws 1.2M, Fig. 7 ,passing through said ,base and'vcap, be forced upv toor madero recede'froin the cylindennsl-de'sired.

p To enable others to m'ake'andns'e my invention, I will proceed' to describe its construction and operation. A *l The* main frame, Fig. 2, is supported upon two-wheels. A' Ai, the distancebe'tweenwhose g" .centersis made' tocorrespond to that between vthe centers of the seeding-cylinders,and conf sequently the` proper-:distance apart for the desired 'width betweenthe rows'otcorn.A Said 'frame-work con'sists'ot" axle B., through which horizontalinear euch end iof its 'square part,

yund also directl'yinthe center, are mortises to receive the projecting ar'm's a wand D.

To' the outer endsotfvarms a arend to their under side is attachedscruper-bar hand to the under side of this bar are Scrapers 25,25 Gn ermee u, unddirectlyinthe rearof este B,"

are ears c c', 'to which eyes c e, Fig. 3, are et-l t-ached by bolts, es seen at c in Figs.l l and 4.. Hounds ff, with the forward end turned up'- Wnrdsufcientl y high toA receive the tongueg, and the sides rearward running parallel with euch other ,and sufficiently far apart for the desired width of the tongue asi'fa'r as B?, Figs.

I, 2, and 4, and tiieu diverging rearward, as.

shown, in Fig.' 2, the whole being constructed ot' one piece of wrought-iron, are 'attached firmly to then-nder side ot' axle ,B by bolts, as

shown at 14, Fig. 4..

Parallel with 4axle B is placed cross-ber F,

slightly notched heiow to receive thehounds., thereby preventing them'froxn becoming bent or spread apart, while at the saine time-itat- 'ords the place ofv support for arm D, on the point ot' which is the fulcrum E. for weighted lever his AThe tongue is secured to hounds j f by ineens v'ot bolt B', while between the point'v ol' hounds f f. and tongue g is placed slide 7L, with rests at different heights to regulate the depth, while set-screws Hbo-id all tirinlytov The upper or additional frainework,Fig. 3, I

is composed of bed-piece 40,ot` any length desired, for the widthjbetween. the rows ot' corn. y 0n each end of this b.ed piece are placed' the boxes 30 30 forth-e seed. Lto be planted. Between thesee'd-boxes and eguinsttheir innerr sides and rmly bolted'to bed-piece 40 are arms or. cross-pieces a a'. To the outer ends of these arms are attached metallic plates b' b',

with eyes at c c, asfseen in Figs'. l and 4, to

metallic plates T l at the proper places te re- 2 Y '36.335l Y l receive `the bolts connecting themV with the main traine-Work at c' c. Near the center of bedpiece 40. is placed. alink or eye, 2, ns seen in Figs. 1, 3, .and 4, tor the recept-ion, of' pendent hook a." of weighted lever nu To thet'ront edge of bed-piece 40, are iirmlyattaehed the ceive the shafts ot cylinders et 4. This plate has on its inner face projections, between which fits tifrht'ly Ybedpiece. 40, while in its lower part is a cavityor slot to receive the neck ot'shoe S', as seen in Figs. 1l and. 4, at r. rhe upper portions ofplates l T' are divided deep enough to allowthe shaft of cylinders It i toY sink to a proper level vor position, and thereby perform the oliiee of otherwise neces-V sary metallic boxings or bearings,while into eachof .the sides of those plates screws' arev passed int'o the seed-boxes, holding them firmly to their places. Those platestherefore perform I center, so that therebythey maybe provided"W the several ofiices of receiving and rinly holding the necks ot' the shoes, receiving and holdingat their proper places the cylinder-shafts, and afford a firm attachmentfor the set-2d-boxes.` Handle I', connected with shaft n, and that with the crankson the cyiinderfshai'ts, affords thev` means of operating the cylinders, when desired, while plate c, attached ,to the top of theat-` tendantsseat s, holds handle I in position;

The attendants seat occupies a po'sit'ionbe-L tween and `is firmly attached to the tops of Metil-boxes 30 30,. The shoes S( are attached to the under side ot' bed-piece 40 by.inf.::1ii.s.'o`` metallic plates T T, as shown at i", Figs. 1 and 11, and hybolts through hanging. stirrupfo,` Fig. 4, and are no support to the frame-work whatever whileiii use,`ast-he Whole is supportedrnainly upontheinain frame-work and very slightly upon the horses necks. Their` construction isl as follows: Two plates ot'v steel,- with.expandingwings forcoverers in therear of their; centers, .and with upward imcliningf` front edges, at iirmly welded together from` their upper poin`s to within abouttwo inchesl of their lower edges, from which lowerlpoint otwelding they gradually recede from each other, thereby-forming an inverted-V-shap''ed` opening in the lower trout-partot the sh0e s, as shown at S", Figi 9, for the purpose ot' forining thedonble furrow, as vshown at w'ugliig. 1,0,to vreceive the seed in a scattered. condition. As the seed falls from the boxes upon the'continuous scatte'rerf, Fig. 10, itis divided by its point androlisdownthe sides into the `different furrowsaudis there covered, thus alording room for the growth ofthe stalks without irowldiug each other. l Shoes cosed tothe bottom arci-'ery liableA to )ecome choked or clogged, and t-lierehy'inopff zratye,Without'theknowl'edgejot the'opemtoi;`l mt .with the herein-described opening int-heir owerV parts: that becomes im possible, because" is the shoe moties forward the earth Aforcing in it openingv 55'.` .removes all adhering fftnnt'terf 'ron1`\i"ltliin .v keeping all clear and tree'. l

Aforced down upon. hounds' f and there' held, producing perfect uniformity ofdepth in planting, which depth may be varied, as desired, by movin g slide l1l so that the hounds may rest on higher or lower notches thereof. In, pass-A ing over the previously-made marks the attendant, having hold of handle I, gives the cylinders a half-revolution byactnating the shaft njust as the front of shoes strikes'the cross-mark upon `the ground, thereby depositing the seed in check-rows, as desired.
